Okay, I'm closing this because at three pages we've only come up with one fact: Some people like the new Admin theme, some don't.
Everyone's opinion is equally valid here. The admin is not 100000% baked. It's going to be tweaked based on how people use it, but it's important to remember sometimes you're just the vocal minority. I certainly am (I want bigger font sizes). The point there is that you may not get what you want, but thankfully WordPress lets you use plugins to edit that.
There are options. For now, we ask that you respect each other and try them out.
